Highest temperature in Seattle on October 28?

根据「Highest temperature in Seattle on October 28?」的最新预测市场数据，交易者已形成强烈共识。

目前，52-53°F 以压倒性的 5,150% 获胜概率主导市场；50-51°F 以 1,900% 位居第二，54-55°F 以 1,700% 排名第三。该市场的下注量已达 $473，反映出市场的高度关注。

为了更好地评估各潜在结果的位置，可依据隐含概率与合约定价将市场划分为三个明显的交易梯队：

🥇 第一梯队：绝对领跑者

• 52-53°F (5,150%)：52-53°F 目前拥有最高概率，深受订单簿青睐。看好该结果的交易者面对的「Buy Yes」合约价为 5,150¢，显示出市场的高度确信。仅该合约就已产生 $369 的成交量。

🥈 第二梯队：主要挑战者

• 50-51°F (1,900%)：作为最可行的替代选项，50-51°F 保持着 1,900% 的成真概率，其「Buy Yes」份额目前成交价为 1,900¢。
• 54-55°F (1,700%)：以 1,700% 的概率位列第三，市场对 54-55°F 持谨慎怀疑态度，除非势头转变，否则视其为外围黑马。

🥉 第三梯队：长尾选项（合计约 0%）

在前三名之外，还有大量宏观变量与冷门结果被持续追踪。尽管单个概率偏低，但它们是投机交易者的重要对冲：

• 替代选项：包括 56-57°F (765%)、46-47°F (510%)，以及 48-49°F (480%)。
• 投机成交：尽管统计概率偏低，像 58-59°F 这类长尾合约仍吸引着可观的关注。

This market will resolve to the temperature range that contains the highest temperature reported at Seattle-Tacoma International Airport (KSEA) on 28 Oct '26.

The qualifying value is the highest temperature reported in the hourly temperature remark of any routine (METAR) observation for Seattle-Tacoma International Airport (KSEA) on that date, in tenths of a degree Celsius as reported. A report whose line begins with SPECI is a special observation and does not count. Every other report is routine, including one issued off the nominal hour and one that carries no METAR or SPECI label.

For How to Read the METAR Report, see: https://polymarket-upload.s3.us-east-2.amazonaws.com/market_products/Weather/How+to+Read+the+METAR+Report.pdf

The hourly temperature remark is the group beginning with the letter T followed by exactly eight digits. After the T, one digit for sign (0 positive, 1 negative) and three for tenths of a degree Celsius give the temperature; the following four are the dew point and are not used. T01390133 is 13.9°C; T10171022 is −1.7°C.

If a routine observation does not carry the hourly temperature remark, the temperature group in the body of that observation governs for that observation, in whole degrees Celsius as reported. It appears as temperature and dew point separated by a slash, with M marking a negative value: 18/12 is 18°C; M11/M17 is −11°C. An observation that reports no temperature in either place is disregarded.

Each market in this event states its range in whole degrees Fahrenheit. The qualifying value is converted using °F = °C × 9/5 + 32 and rounded to the nearest whole degree, with a value ending in exactly half rounded up to the next higher whole degree, and that whole Fahrenheit value determines which range contains it. For example, 18.3°C is 64.94°F and counts as 65°F; 17.8°C is 64.04°F and counts as 64°F; 19°C is 66.2°F and counts as 66°F; −22.5°C is exactly −8.5°F and counts as −8°F.

An observation counts if its time stamp, converted to the station's local time (including any daylight-saving shift in effect), falls on the observation date.

This market will resolve at the issuance of the first METAR observation for the station on the day following the observation date or by 11:59 PM ET on the day following the observation date, whichever comes first. Resolution is determined from the observations the resolution source shows for the observation date.

In the event that the Aviation Weather Center has published no routine observation reporting a temperature for the observation date by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that neither source has published data sufficient to determine a temperature for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.

The report the resolution source shows for a given observation time is the one that counts, whether or not it is marked as a correction (COR). Changes to observations within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered. Where the first routine observation for the following date is published before that deadline, resolution is determined from a read taken after it. Where it is not, resolution is determined from a read taken at that deadline.

In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

The resolution source for this market will be the routine observations for Seattle-Tacoma International Airport (KSEA) published here:
